The pipette was then filled with 25.0mL’s of acetic acid and then drained into a conical flask, to speed up the process both of the conical flasks were filled with 25.0mL of the acetic acid. 8. Three drops of phenolphthalein was then added to the flask with the acetic acid. 9. The conical flask was then positioned to just under the burettes dropper which had its stopcock opened to allow a medium drip rate and had the sheet of filter paper slipped under it so that the colour could be seen more earily.
6- Place only the edge of the Q-tip at the top the Flame. 7- Remove it when you see the of light being given off to avoid burning the Q-tip. 8- Clean up procedure: Discard used Q-tips to the bin, cover back compounds and put them up in a safe place, pour away distilled water in the sink, disconnect the Bunsen burner and clean it if stained,clean the lab test surroundings with paper towel to ensure no stain is left, wash your hands remove your goggles only when all equipments have been placed in safe places.

Be sure the ink stays above the water and the paper stays in the water. 6. Allow the water to soak up the strip and watch what happens to the ink drop. 7. If the ink you are testing does not spread out, re-test it using rubbing alcohol.
4) Swirl the flask in circular movements to mix the substances. 5) Put the flask under the buret of NaOH solution, make sure the buret’s tip is inside the flask’s opening 6) Observe and record the initial volume of the NaOH buret. Note the markings on the buret. 7) Begin the titration by twisting the lever on the side of the buret until small drops come out. Keep swirling the solution until a pink color is visible throughout from the phenolphthalein.
: wear gloves, offer a drink, use medication pot or dispensing device such as an inhaler or syringe. Check that the medication has been taken then sign the MARS sheet. Document and report and missed medication, inform my manager and contact NHS Direct or GP for advice. 2.1 Medications fit into four groups: *GAL-General Sale List *P-Pharmacy *POM-Prescription Only Medicines *CD-Controlled
The L5-S1 interspace was identified under fluoroscopy, the skin overlying the interspace was sterilized and infiltrated with 2 – 3 mL of local anesthetic (lidocaine 2%), a 20-gauge, 15 cm needle with a 30° short bevel (Chiba needle) was inserted perpendicular to the skin at the center of the L5-S1 intrelaminar space under anteroposterior fluoroscopic vision. Under lateral fluoroscopic control, the needle was then advanced towards the intervertebral disc so that it penetrated the thecal sac. After confirming the avoidance of nerve injury by the absence of paresthesia, the tip of the needle was advanced through the intervertebral disc until it exited at its anterior surface. Correct positioning was confirmed by administration of 4 mL of soluble contrast medium in both lateral and antero-posterior fluoroscopic
Dip the slide into Eosin solution for 7 times and remove the excessive solution with a paper towel. 3. Dip the slide into new methylene blue for 9 times and remove the excessive solution with a paper towel. 4. Use the incinerator to allow it to dry completely.
4. Any hanging drop was removed from the jet, and the sodium hydroxide was then drawn up using the pipette, to above the graduation mark and allowed to run into the sink. This process was the rinsing of the pipette. 5. Sodium hydroxide was again drawn up using the pipette, to above the graduation mark, where the meniscus was allowed to fall until the bottom of it was rested on the graduation mark when viewed at eye level.
From the cartridge, 0.4 mL of water was removed under a laminar flow using a sterile disposable syringe.The weight of the cartridge was again taken and 0.4 mL of buprenorphine as buprenorphine hydrochloride was injected into the cartridge and reweighed. Each cartridge contained 0.05 mg/mL(0.3*0.4/2.35) of buprenorphine. The prepared cartridges were stored at room temperature away from dust and direct light, till
When the liquid above the precipitate was clear, the solution was tested for completeness of precipitation when a few drops of BaCl2 solution were added from a pipette. Next, filter paper was place into the funnel and streamed with distilled water. A clean 400mL beaker is placed under the funnel and the precipitate was filtered through. When all the precipitate was filtered and removed from the beaker the residue is washed with distilled water. About 3mL of the wash water is collected in a small test tube.
